The Orioles once again have an intriguing lineup in place heading into the 2018 season, but face similar problems with their rotation. Can they fix it in time to make the postseason?

Baltimore struggled last season in a tough AL East. While Manny Machado was floated as a possible trade piece this winter, he's still on the roster playing a new position this season.

Here are three things on the Orioles' to-do list:

1. Find out if Machado can succeed at shortstop

With just one year left on his contract, Machado, was linked with a number of teams this offseason, but his desire to play shortstop helped keep him in Baltimore. The Orioles will move Tim Beckham to third base, which gives them an athletic infield.

Machado hit .259 with 33 home runs and 95 RBIs last season, but the Orioles have to ensure switching positions won't affect his hitting. The Orioles need to use spring training to decide if the switch is worth it. Machado's bat makes him elite, and he's won two Gold Gloves at third base.

2. Add a couple more arms to the starting rotation

Baltimore's rotation is in desperate need of a makeover. Kevin Gausman and Dylan Bundy appear poised to lead the way right now, but the Orioles lack depth behind them. Gabriel Ynoa, 24, could be an X-factor, and the Orioles did sign Andrew Cashner, but Baltimore should add a couple more established names this spring if it wants to compete.

Baltimore had been linked with Jake Odorizzi (recently traded to Twins) and Astros long reliever Collin McHugh, and some intriguing free agents remain on the market (a Jake Arrieta reunion?). It appears the Orioles are willing to bring a few more pitchers in this spring, which should help them remain competitive in the AL East.

3. Figure out right-field opening

The Orioles would likely rather have Mark Trumbo serve as designated hitter, which leaves a huge hole at right field. Austin Hays, 22, who had 13 hits in 60 at bats last season, seems like the leader to earn the job, but it wouldn't hurt Baltimore to add the likes of Carlos Gonzalez or Carlos Gomez for competition.
